Definitions

  • the invention relates to a method for producing the sheathed clamping beam.
  • the invention also includes an apparatus for carrying out the method.
  • DE 2 944 878 A discloses a method for applying a metallic protective cover to prestressing steels.
  • the object of the invention while avoiding the aforementioned drawback, to produce a clamping bundle, which has a sheath that can be applied by simple means without high cost on the clamping beam.
  • the tensioning beam is produced by the method according to claim 1 with simple means and low labor.
  • the measure according to claim 5 forms a preferred development the device according to claim 4.
  • the device shown in a simplified representation in FIGS. 2a and 2b has on a longitudinally extending frame 1 or table or the like.
  • a drive device 2 for guiding and locomotion of a commercial plastic tube 3 in any length, which is oval in cross-section with rounded ends, as well as preferably mutually parallel tendons 4, in the form of monolayers, the most, as shown in FIG. 1, with a corrosion protection 5 in the form of grease, a plastic jacket or the like. can be provided.
  • a common drive for the tendons 4 and the plastic tube 3 is provided, which consists in the present case of several consecutive vertical rolls 2A, which are rotatably mounted, wherein at least one of them, preferably the output side, is driven.
  • the drive rollers 2A guide the tendons 4 above the plastic tube 3, so that the plastic tube 3 and the tendons 4 are moved at the same speed in the direction of the arrow A one above the other, as shown in Fig. 2A.
  • rollers 6 Following the drive device 2 are superposed rollers 6, rollers or the like. for guiding the plastic tube 3 of a subsequent cutting device 7 designed as a rotating cutter disc, which cuts open the highly guided plastic tube, as shown in FIG. 3B, at the apex of its rounded end.
  • a subsequent cutting device 7 designed as a rotating cutter disc, which cuts open the highly guided plastic tube, as shown in FIG. 3B, at the apex of its rounded end.
  • a gap or folding device 8 is provided, through which the incision or Gap 9 of the plastic tube 3, as shown in FIG. 3C, is widened. Expediently, the expansion takes place only in the region of the elasticity of the tube material.
  • a deflection channel 10 is provided which deflects the tendons 4 down and introduces through the widened slot 9 in the plastic tube 3, whereupon the tube 3, due to the spring force closes and then, as illustrated in Fig. 2b, is welded by a welding device 12, so that a band-shaped clamping beam of Fig. 3d is formed.
  • the spring force of the pipe material for closing the plastic pipe 3 is not sufficient, can be provided on the welding device 12 laterally acting on the pipe wall pressure rollers or pressure rollers. This measure can be done as a precaution, if the spring force is sufficient.
  • a means for supplying cement is provided, so that the spaces between the tendons and the plastic pipe 3, as shown in FIG. 1 and FIG. 3e, are provided with a filling material or a filling 11.
  • cement of course, plastic or a fat-like mass or the like. be used as filler.
  • the arrangement of the device for supplying cement may also be provided in front of the welding device.
  • At least one feed lance may be provided for introducing the filling material, which is introduced into the plastic tube 3 or the plastic tube prior to the welding of the cut or gap 9, so that this or this is guided past the feed lances and filled with the filling material.
  • the lance can extend up to or in the area of the weld or behind. Instead of such a supply of the filling material, this can also be introduced as a prefabricated band with the tendons 4 in the cut or slotted plastic tube 3 or in the cut or slit plastic tube.
  • drive rollers 13 may be provided, which feed the finished tensioning bundle according to Fig. 3f of a reel, not shown.
  • Hiebei encloses the coat or the plastic tube 3 or the plastic tube preferably the tendons, leaving a narrow gap at best to the extent of manufacturing tolerance.
  • guide rollers 14 may be provided along the guide track of the plastic tube 3 or the plastic tube in the region of the welding device.

Claims (5)

  1. Procédé de fabrication d'un faisceau d'éléments de tension, qui est constitué de plusieurs éléments de tension (4), lesquels sont recouverts d'une gaine commune, caractérisé en ce qu'un tube en matière plastique ou tuyau en matière plastique (3) est refendu et évasé le long de la surface en coupe ; les éléments de tension (4) sont alors introduits dans la fente ouverte ainsi formée, après quoi le tuyau en matière plastique ou le tube en matière plastique est fermé, de préférence du fait de sa propre élasticité, et les surfaces en coupe à souder sont soudées.
  2. Procédé selon la revendication 1, caractérisé en ce que, avant la procédure de soudage, au moins une lance est introduite dans le tuyau en matière plastique (3) encore ouvert ou tube en matière plastique encore ouvert, au travers duquel une matière de charge (11) est introduite dans la gaine commune formée par le tuyau en matière plastique ou le tube en matière plastique, autour des éléments de tension (4), au niveau de, en amont ou en aval de l'emplacement de soudure.
  3. Procédé selon la revendication 1, caractérisé en ce que, avec les éléments de tension (4), on introduit dans le tube en matière plastique refendu ou dans le tuyau en matière plastique (3) refendu, une matière de charge (11) pour remplir les espaces entre les éléments de tension (4), et entre ceux-ci et la gaine, sous la forme d'une bande préfabriquée.
  4. Dispositif permettant de mettre en oeuvre le procédé selon la revendication 1, caractérisé en ce qu'on prévoit des cylindres (13) successifs dans la direction longitudinale, permettant de guider et d'entraîner ensemble un tube en matière plastique, tuyau en matière plastique (3) et les éléments de tension (4), un plateau porte-lames rotatif (7) ou similaire permettant de refendre le tuyau en matière plastique (3) ou le tube en matière plastique dans la direction longitudinale, un dispositif (10) permettant d'introduire les éléments de tension (4) dans le tube en matière plastique refendu ou tuyau en matière plastique refendu (3), et un dispositif (12) permettant d'aboucher par soudage la fente ou découpe du tube en matière plastique ou tuyau en matière plastique (3).
  5. Dispositif selon la revendication 4, caractérisé en ce que les cylindres (13) successifs dans la direction longitudinale sont respectivement disposés en pouvant pivoter autour d'un axe vertical, moyennant quoi au moins le cylindre du côté sortie des cylindres (13) est entraîné.
